Ms660 jigsaw

[Ttxpc]

Hi guys
Been keen to do one of these for a while, have one on the way from huztl to Australia, have some oem parts such as the wrist bearing and pin clips on the way as well, no real questions just wanted to join in and say hi

Picked up an 032 today, strip n look over tomorrow woot

 

[Ttxpc]

Sooo got it assembled today.
Few small issues, decompressor valve was terrible, had to seat the valve to seal, chain brake parts were terrible and parts missing... Ratted most from a parts saw...

Cleaned up cylinder without changing the port timings, could not do a gasket delete, had piston/cyl head interference without gasket,. 020" Squish with gasket, port timings were 98 exh open, 90 inlet close and 128 transfer open, removed muffler baffling and opened up outlets, less than ideal, but idles well and performs very good, hard nose 30" bar in yellow box
No bar oil at first, suction tube was blocked one way (toward pump of course) only via defects in the hose, got that sorted, overall happy indeed, will run a few tanks then port the cylinder a little and see

The transfer and intake #s seem very high. Usually intake much over 80 will suck a lot of gas.

What P+C is it? Any vids of saw cutting?

 

[huskihl]

That's probably the ft cylinder. He just got one that was a little lower is all. Mine was 94 124 86

 

[Ttxpc]

Farmertec cylinder, transfers seem low to me, would prefer them to open 8 deg earlier, and inlet to close 10deg earlier, looking forward to running some fuel through it today
No vids of it cutting, need an assistant

 

[MustangMike]

For an assistant, I used duct tape and a stool!

 

[Ttxpc]

Well the saw runs great, cut down a fair sized dead yellow box and processed it with a couple of friends.

Lil China uses an awful lot of fuel haha, the oiler is anaemic at best, total junk in reality, half a tank of oil to 3 tanks of fuel, resorted to manually oiling the chain, ordered a high flow unit to replace it.

Overall pretty happy with it, most fun jigsaw I've done
Run a few more tanks once I get a decent oiler

 

[Wonkydonkey]

Does it free port at tdc ?, I had one that did, and although it ran like stink, I think fresh fuel was being sucked straight out the exhaust.

 

[Ttxpc]

No doesn't freeport but the inlet is really low, might play some epoxy when . I pull the jug to port it

 

[MustangMike]

All the ones I have built Oil just fine.

 

[Ttxpc]

Thinking the oiler got damaged in the first couple minutes, hose was blocked, fixed that, it does oil but no where near enough for a 30" hardnose in dirty yellow box, checked the system thoroughly
All my other stihls use pretty much one for one, tank of oil to a tank of fuel

Go get ya a oem worm gear and see if that fixes it.

 

[Ttxpc]

Got a oem high flow knock off on the way, ground the control bolt to bring the worm out another. 010" seemed better but not enough, not enough swash on the worm or miss timed cut out etc

 

[Ttxpc]

New oiler is a success, spent a few hours today, put 3 or 4 tanks through Lil China, made a lot of sawdust and had a ball, the ms660 for the heavy lifting and the 025 for the light stuff, the 38mag didn't get a look in

 

[bottlefed]

I just built my first FT660 and had the exact same deal. Piston hit head with no gasket, oil pump was useless.

 

[MustangMike]

I have had to sand bumps in the squish band with sandpaper on an old piston (in one of my threads), but I have not had any problems with the oilers, but I'm very careful installing them.

 

[stihl_head1982]

I had heard that Hutzl had discounted the price to less than $150 shipped on the cloned MS660.
A look at their site revealed that it was not true. Shows $186 then you have to estimate shipping cost(?)
Is there an inside track on these, or a recommended way to purchase them that cheap.

 

[dmitriy]

I got mine for $130 (shipping was $100 with a bar and extras). Just wait around and a sale will pop up. I waited about a month since missing the last sale.
